The GOST 8732 standard specifies the requirements for seamless hot-formed steel tubes with a galvanized surface, designed primarily for gas transportation applications. These tubes are manufactured using high-quality carbon steel, ensuring durability and reliability in gas transportation systems.
| Property | Value |
|---|---|
| Standard | GOST 8732 |
| Material | Carbon Steel |
| Surface | Galvanized |
| Manufacturing Method | Hot-Formed |
| Outer Diameter Range | 10mm - 426mm |
| Wall Thickness Range | 1.5mm - 40mm |
| Length | 4m - 12m |
The chemical composition of the GOST 8732 seamless steel tubes with galvanized surface is as follows:
| Element | Composition Range |
|---|---|
| Carbon (C) | 0.07% - 0.13% |
| Silicon (Si) | 0.17% - 0.37% |
| Manganese (Mn) | 0.35% - 0.65% |
| Sulfur (S) | 0.035% max |
| Phosphorus (P) | 0.035% max |
The mechanical properties of these carbon steel tubes conform to the standards set by GOST 8732:
| Property | Minimum Value |
|---|---|
| Yield Strength (Rt) | 235 MPa |
| Tensile Strength (Rm) | 410 - 550 MPa |
| Elongation (A) | 24% min |
| Impact Toughness | No less than 27 J/cm² |
The steel grade used for GOST 8732 seamless steel tubes with galvanized surface is 10, 20, 35, 45, 10G2, and 20Ch.
These seamless steel tubes find extensive application in gas transportation systems. Due to their hot-formed galvanized surface and robust carbon steel composition, they are well-suited for conveying gases under various temperatures and pressures. Their durability, corrosion resistance, and high mechanical properties make them a reliable choice for gas transmission pipelines.
